GENERAL<strong>Chromalox</strong> Type <strong>AEPS</strong> explosion proof electric strip heatersare ideal for the control of moisture in mechanical conveyor lines,vibrating feeders or other automatic material h<strong>and</strong>ling equipment.This heavy-duty strip heater safely prevents freezing of the materialstransported.1. <strong>Heat</strong>er construction characteristics:a. Designed for maximum heat dissipation. Its heavy 3-inchwide aluminum extrusion protects a .475” diameter singleend tubular heating element <strong>and</strong> provides adequate protectionagainst unexpected fusion failures.b. <strong>Heat</strong>er lengths available up to 10 ft. maximum.c. Vibration resistant.d. All exposed surfaces of the heater are aluminum.The system designer is responsible for the safetyof this equipment <strong>and</strong> should install adequateback-up controls <strong>and</strong> safety devices with theirelectric heating equipment. Where the consequencesof failure could result in personal injury orproperty damage, back-up controls are essential.INSTALLATIONELECTRIC SHOCK HAZARD. Disconnect all powerbefore installing or servicing heater. Failure to doso could result in personal injury or property damage.<strong>Heat</strong>er must be installed or serviced by aqualified person in accordance with the NationalElectrical Code, NFPA 70.1. Before installing, check your strip heater for any damage thatmay have occurred during shipment.2. Check to insure that the line voltage is the same as that stampedon the nameplate.3. Channel in extrusion facilitates mounting to any non-combustiblesurface. Clamps are supplied or bolt hole can bedrilled through groove in extrusion plate.4. <strong>Heat</strong>ers are furnished with a packet that includes holddownclamps <strong>and</strong> wire nuts for field wiring. Holddown clampsshould be mounted so that the maximum distance betweenclamps does not exceed 18”. The 1/4” bolts (by others) shouldbe tightened <strong>and</strong> backed off a quarter turn to allow for expansion.FIRE HAZARD. Since electric heaters are capableof developing high temperatures, extreme careshould be taken to:a. Avoid contact between heaters <strong>and</strong> combustible materials.b. Keep combustible materials far enough awayto be free of the effects of high temperatures.(See page 1)WARNING: (Group B): to prevent ignition of Group Batmospheres, conduit runs must not exceed 3/4 inchin size <strong>and</strong> all conduit runs, 1/2 inch size <strong>and</strong> larger,must have a sealing fitting connected within 2 inchesof the terminal enclosure.NON-COMBUSTIBLE SURFACEHORIZONTAL MOUNTING R.H.CORRECTCORRECTINCORRECTVERTICAL MOUNTINGVertical Mounting — When theheater is vertically mounted, theterminal housing must be at thebottom.HORIZONTAL L.H.CORRECTHorizontal Mounting — When theheater is horizontally mounted, theterminal housing can be positionedL.H. or R.H.
